Subdominant – Definition
The subdominant is the fourth scale degree and the chord built on that degree. It is one of the three primary harmonic functions in tonal music, together with the tonic and dominant.
What is the Subdominant?
In the key of C major, the subdominant chord is F major. The subdominant often creates a gentle sense of movement away from the tonic before leading toward the dominant or returning directly to the tonic.
Its harmonic function plays an essential role in establishing direction and balance within chord progressions.
Why is the Subdominant important for pianists?
The subdominant appears in countless chord progressions found in pop, rock, blues, gospel, and many other musical styles. Learning to recognize its sound helps pianists identify harmonic movement and play songs more confidently.
Understanding the relationship between the tonic, subdominant, and dominant is one of the foundations of functional harmony and effective accompaniment.
